SAFETY-PIN.

Specification of Letters Patent.

Patented Nov. 6, 1917.

Application filed January 11, 1917. Serial No. 141,740.

To all whom it may concern:

Be it known that we, JOHN F. DOYLE, J r., and MANUEL D. AVILLAR, both citizens of the United States, and residents, respectively, of Garden City, in the county of Nassau and State of New York, and New York city, in the county and State of New York, have invented certain new and useful Improvements in Safety-Pins, of which the following is a specification.

This invention relates to a safety pin of novel construction which may be readily manipulated, is not apt to tear the clothing, and is securely locked in its closed position.

In the accompanying drawing:

Figure 1 is a side view of a safety pin embodying our invention, showing the pin closed;

Fig. 2, a similar view showing it open, and

Fig. 3, a longitudinal section, partly in side view.

The device comprises essentially a holder 1, which is formed of a length of wire or similar material, the ends of which are first bent into parallelism as at 2, and then toward each other. Of these, the rear end is coiled into a cylindrical spiral, constituting a keeper 8, while the forward end is coiled into a conical spiral constituting a guide 4 that is axially alined with the keeper. The wire shank or body 5 of the pin which is axially movable within. the guide, has a flattened point 6 which may be received within the keeper 3 but is of a width greater than the diameter of the innermost coil of guide 4, so that the pin cannot become dislodged from the holder in its open position (Fig. 2). The outer end of shank 5, is bent into the form of a spring eye 7, having a toe 8, that converges toward shank 5. Eye 7 constitutes a handle for manipulating the device, and likewise a spring which tends to retract toe 8 slightly from shank 5. Toe 8, is provided with a notch 9 adapted to engage the outermost convolute of guide 4, and thus lock shank 5 in its closed position.

In use, shank 5 is pushed with its point 6 through the garment and thence into keeper 3, during which movement, toe 8 will enter the widened mouth of the guide and lock the pin in position by engaging the outermost convolute of the guide. To. open the device, the shank is drawn axially outward, with a force sufficient to overcome this engagement.

It will be seen that the in can be operated in a very handy manner inasmuch as its eye is always accessible and that the axial movement required for opening and closing may be performed with greater facility than the sidewise movement heretofore generally practised.

\We claim:

1. A safety pin comprising a holder having a keeper at one end, and a convoluted guide at the other end, an axially movable pin extending through said guide and adapted to be projected into the keeper, said pin being provided with a resilient eye having a notched toe adapted to engage one of the guide-convolutes.

2. A safety pin comprising a holder hav ing a convoluted cylindrical keeper at one end, a convoluted conical guide at the other end, an axially movable pin extending through said guide, and adapted to be projected into the keeper, said pin have a flattened point at one end and a notched spring-controlled toe at the other end, which toe is adapted to engage one of the guide convolutes.
